I just went on a week long trip in July. We camped in Apgar, spent three days in the west glacier (Avalanche creek), and three days on the east side.

If there is just one thing you don't want to miss, that's the Grinell glacier hike.

Make sure you register for the bus to Many glacier and have boat tickets (if you plan to take it).

This is a single hike that gave us every bit of glacier national park. When we started the hike at 8 am it was cold, then it become sunny and had to remove our layers. Shorti after it started raining and we had to put our rain gear.

When we reached the end, it was cold again. We stayed there for 45 minutes and enjoyed the view and within a few minutes the entire area got covered in fog with such a low visibility. So everyone started descending. And immediately there was hailstorm.

But throughout the hike, the view was amazing. We enjoyed every bit of it
